==> STAGING COMPLETE (3 inputs)

Matplotlib created a temporary config/cache directory at /tmp/matplotlib-j7ae_u71 because the default path (/.config/matplotlib) is not a writable directory; it is highly recommended to set the MPLCONFIGDIR environment variable to a writable directory, in particular to speed up the import of Matplotlib and to better support multiprocessing.
Fontconfig error: No writable cache directories
No chrX found in sample; is the input truncated?
